So I say we commit my patch: albeit suboptimal, and somewhat reeking of cargo-cult programming, it solves the OP issue. If someone then wants to venture in refactoring, fixing and cleaning up the elisp support in Automake -- be him my guest! As for more, I'm not knowledgeable nor motivated enough to venture in something like that at the moment.

But then, I guess all the current implementation of byte-compilation for elisp sources is probably brittle and buggy in such a setup anyway, I guess, so my misgivings might be unjustified: <http://lists.gnu.org/archive/html/automake/2009-10/msg00013.html> Anyway, I'd rather not touch the existing code, for fear of introducing regressions. But patches would be mostly welcome (if coming with proper testsuite enhancement). Thanks, Stefano
